Materials move within the cell 's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion. ... Diffusion: Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. ... Active transport requires energy, because protein machines actively grab molecules on one side of the membrane and push them through to the other side

Isolation can be due to behavioral, geographical, or temporal barriers. <span>Speciation can take place in two general ways. A single species may change over time into a new form that is different enough to be considered a new species. This process is known as anagenesis. More commonly, a species may become split into two groups that no longer share the same gene pool. This process is known as cladogenesis. There are several ways in which anagenesis and cladogenesis may take place. In all cases, reproductive isolation occurs. Hope this helps! </span>

Which organelle in the table is correctly matched with its function?
allsm [11]

The organelle in the table that correctly matches its function is the ribosome because it produces proteins.

<h3>What is a ribosome?</h3>

A ribosome is an organelle that functions as a protein factory in the cell, whereas vacuoles contain dissolved materials and store water.

Mitochondria are energy producers by the process of cellular respiration, and lysosomes contain hydrolytic enzymes.

In conclusion, the organelle is a ribosome that produces proteins.
